India Chooses Arm's Neoverse for National Chip Design Push, 18 May 2003

If everything goes to plan, India's Aum Arm CPU will be a strong entry into the supercomputing field. Crucially, it'll be a homegrown one - even if not dramatically so, at least in its first iterations. Much work was clearly put into advancing the memory subsystem as a whole, and in general, memory is easier and more available to source than the TSMC 5 nm chips Aum will be made of. Customizing the CPU core itself could be C-DAC's next step, preparing the way for India and adding momentum to the "chip nationalization" process in other countries. China too has had an interest in Arm, by the way; but that is an entirely different story.

Beijing bans Chinese companies from using Micron chips in critical infrastructure, 21 May 2023

Idaho-based Micron is the largest memory manufacturer in the US. The Chinese market accounts for about 10 percent of the firm's annual revenue, though the majority of companies importing Micron products into China are manufacturers making devices for sale in other parts of the world. According to The Wall Street Journal, the CAC's ban does not apply to non-Chinese firms in China.
